DISK WATER-METER.

Specification of Letters Patent.

Patented April 14, 1908.

Application filed December 22, 1906. Serial No. 349,015.

citizen of the United States, residing at Newark, in the county of Essexand State of New I and there are less crevices for Jersey, have inventedcertain new and useful Improvements in-Disk Water-Meters; and I do erebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

This invention relates to a water meter, and is particularly ada' tedtonieasure a fine stream passing throug a pipe, is'extremely sensitive,being built so that the disk in the meter will not stick, and is alsodesigned to providea meter that has a small number of partsandconsequently there are less joints requiring finishing to make themwater tight, and it is also easier to assemble the meter,

the accumulation ofdirt and grit.

This invention is an improvement on the style of water meter describedand illustrated in my Patent No. 818,430 of April 24, 1906', and theimprovement lies in a new base portion that has the passages for thewater integral in the base portion, and also provides for an easierrunning connection between the (gieaii'ing of the registering mechanismand the Another new feature of this meter is the construction of a webap roximately diametrically opposed to the ividing partition of the diskchamber, and antifriction bearings between the disk and the opposedsides of the partition and the web toprevent binding of the disk on thepartition or web when the disk is tilted, and the disk is also made ofrubber in a way to'pr event its being warped.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a central vertical section of the meter with the registeringmechanism in elevation. M Fig. 2 is a section of the base portion online 2 in Fig. 1. Fig. 3 is a top viewof the base portion with the diskin place, the partition and web of the disk chamber being shown insection, and Fig. 4 is down on the top I passing a plan of the diskpartly broken away at one point to show the stiffening or anti-warpingeature.

In this improved me'ter I employ a base portion 10 that is preferablycast and with indentations at all suitable points so as to lighten itwithout weakening. the structure, and this base portion is su ported onthe feet 11. A cover 12, with tiie flanges 13, sits of the base portionand forms, with the central portion of the base portion, a disk chamberin which moves, in the manner usual to these disk meters, a disk 15supported by the ball 14 which is held fbetween the cover 12 and thecentral po tion of the baseportion 10. At a suitable point in the diskchamber is arranged a partition 16, shown in Figs. 1 and 3, thispartition causing the water to go around in the disk chamber to move thedisk, the water coming in throu h the inlet passage 17 which is castdirectdy into the base portion 10, and is connected with the inlet ort18. The Water passing in through the inlet port 18 passes around throughthe passa e 17 to the other side of the meter, and fo lowing the courseof the arrows in F'ig. 3, it actuates the disk 15, and around thepartition 16, runs out throu the outlet port 19. The inlet port and t eoutlet port have suitable screwthreads 20 on their exterior forattaching the meter to a pipe line.

It has been found that in the gyrations of the disk, and when it tiltedat right angles to the partition, there is apt to be a binding if thereis a very small volume of Water assing through the meter, andconsequently aving little force. This has also been present when rollingbearings have been employed on both sides of the artition, and in orderto overcome this di cultly, I have installed a web 21 projecting intotie disk chamber approximately opposite the partition 16, this web notprojecting into the disk chamber far enough to interfere with the freeflow of the fluid. Bearing on one side of the web and on theoppositeside of the partition, are a pair of rollers 22, these rollersbeing given plenty of room for operation by reason of the slots 23 and24, for the partition 16 and the web 21 respectively. These rollers arepreferably placed on the side from which the flow is apare secured tothe driving shaft 36 of a train hard rubber in most cases, and is'easilymade lug to which is secured a conical b ock 27 which has a peripheralroove 28. The

and similar structures, the heat travels back -I claim is:

proaching, and thus take up the thrust and 'allow' a free action of thedisk under all conditions.

Sitting on to of the cover 12 is a ca 26 which has the iiange 25, bymeans of .w ch it is secured to the cover 12. The cap when placed inosition is centered in its relation to the,disii,-and when placed inposition is fixed with this relation in mind and irrespective of the reistering mechanism to be hereinafter described. This cap is .of'asomewhat dome like shape, and has a central de ending screw or post 29passing t ough'and projecting from the ball 14"of the disk, is provided,on its end, with a rollerv 30 which, when the disk is operated, rollsaround in the groove 28, and the portion 31 which .is referably arotating sleeve, engages one o the arms 32 which is fastened to theshaft 33, and on the top of this shaft 33 the projecting arms 34 engageanother set of arms 35 which of gearing 37. This whole structureisincased in a suitable casing 10 and any suitable connection is used totransmit power to a suitable registering mechanism 38 which can be readthrough the sight glass 39,- the whole being adapted to be covered, inthe usual Way, by a lid 40. It will be seen from Fig. I particularly,that a veryeasy running device is constructed, and that the roller 30running in the groove 28 makes a very easy running device, and thiscoupled with the rollers on the partition and the small web, in the diskchamber, will allow the disk to be tilted under the very slightestpressure.

Whenwater meters of the disk t e are placed in positions in proximity tooilers along the feed ipe, it not much water, or no water atall is eingused, and heats'up the water inthe meter, and one heating of thiskind-is liable to warp the disk, as it is made of mis -shapen. I insert,when molding this disk 15, radial wires or small rods 41 which tend tohold the disk perfectly flat, do .not. make it too heavy, and will atall times keep the disk stifi. 1 i

I wish to emphasize the fact that the roller 30, running around in thegroove 28 of the block 27, assists in'holding down the ball and takingthe wear off the upper surface on which the ball 14 rotates. It hasbeenfound, in water meters of this class, that the wear on the top ofthe ball is greater than on the bottom, and this wheel 30, running inthe groove assists in counteracting the tendency of the ball and thedisk to ride upward.

Having thus described my invention, what 1. An'improved water metercomprising a port.
